MANUFACTU RE OF PLATE-GLASS.

SPECIFICATION forming part of Letters Patent No; 434,400, dated August12, 1890.

Application filed March 21, 1.890. Serial No. 344,790. (No model.)

I To a/ZZ whom it may concern.-

-Glass; and I do declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, and to the letters of reference markedthereon, which form a part of this specification.

My invention relates to certain novel improvements in machinery which isadapted for molding plates of glass, and also to give dierentconfigurations to the glass; and the nature of my invention consists inthe following mechanism, which will be fully understood from thefollowing' description and claims, taken in connection with the annexeddrawings, in which- Figure l is a perspective View illustrating myimproved molding devices, and also showing the railway-connectionthereot` With an annealing-furnace. This view shows the crane and alsoshows the rectangular reciprocating molding-plate at one end of thetrack. Fig. 2 is a bottom view of the track, the coil of heaters forheating the bed-plate, also illustrating the gearing for givingreciprocating movements to said bed-plate, and also showing theshifting-gearing for giving the traversing movements to this plate. Fig`3 is a vertical view of one end of the machine, the crane being removed,showing a plate-carrier truck mounted on a hinged track on its way witha glass plate to one of the tracks in the annealing-furnace. Fig. fl isa vertical side view of. a series of plate-trucks arranged in part of anannealing-furnace, showing the glass plates thereon and the rail-trackson which said trucks are supported in said furnace. Fig. 5 is a verticalcross-section through the pressin g-cylinder and the heaters thereon;also showing the heaters for the reciprocating bed and the iiexible tubewhich furnishes gas for the heaters. Fig. 6 is a top view of Similarletters of reference indicate corre- Y spending parts in the severalfigures.'

Referring to the annexed drawings by letter, A designates a rectangulartrack-frame, which is supported upon legs A A in ahori- Zontal position.This frame is rigid in every part, and is sustained upon a substantialbase, so that there shall be little or no vibration. The ways a a areparallel to each other, and

these Ways aord tracks,-which are horizontally groovedat b for trulyguiding a longitudinally-reciprocating bedl B, which is provided withangular guiding and stay ribs b at the ends of this bed, thelongitudinal eX- tensions b2 of which are double-beveled at their ends.

At or near the middle of the length of the frame A and rigidly securedupon the longitudinal ways a a thereof are pillow-blocks c c', whichafford j ournal-bearings for the tubular journals d d of a hollowcylinder D, which cylinder may be plain-faced, or on its face diierentcharacters may be made, which will be impressed into the soft glass.This cylinder D is provided internally and centrally with a gas-pipe D',having numerous gas-jets for heating the cylinder and keeping it at atemperature which approximates the temperature of glass when in a moltencondition. This cylinder, as well as the reciprocating bed-plate, isheated and kept at a certain degree of heat necessary to retain theglass in a proper condition for manipulation and transfer to theannealing-furnace. I therefore employ, in combination with the bed-plateB, a serpentine heater S, which is connected to a natural or anartificial gas-feeder by a flexible tube S', which latter allows the bedB to reciprocate, and at the same time the flame can be maintained.

On the lower side of the bed B and alongside of the parallel bars a aare rack-bars a a', which are rigidly secured to the said bed. Thesebars are clearly shown in Fig. 2. With these racks a a engage toothedpinions ZJ b', which are keyed on a horizontal transverse shaft E. Onone end of the shaft E is keyed a cog-wheel F, which engages with oneend of a similar wheel F on the hollow journal of the cylinder D, thustransmitting by said twin wheels F F a uniform movement, which issynchronous with the reciprocating movements of the bed-plate B. On theopposite end of the shaft E to the end on which is keyed the cog-wheelF, I apply two belt-pulleys II Il', both of which turn loosely on saidshaft. The pulley II is run with a straight belt from a drum on a maindriving-shaft, and the pulley I-I is run from the same drivingshaft by acrossed belt. Between these two belt-pulleys and on the shaft E isloosely applied a clutch-bearing arm I, to the upper end of which ispivoted a short angular rod J, which is pivoted to an arm J', that isrigidly secured to a longitudinally-movable rod K, which extends fromone end to the other of the main supporting-frame A. This rod issustained by short elongated hole-brackets 7c c, and its ends arepivoted to the outer ends of short levers l, which have their fulera atZ on brackets secured to the transverse end bars A2 of the main frame.The inner ends of this short lever Z are formed with tubular bosses m,through which pass longitudinallyshifting rods r,which protrude freelythrough the said end bars A2 and are endwise adj ustable by means ofbinding-screws r. My objectis to transmit a continuous rotative motionfrom a prime motor, a reciprocating rectilinear movement to the bed B.The ends of the bed itself impinging alternately against the rods r 7^,shift the rod K endwisc, which, acting through the medium of theclutching device I, automatically reverses the movements of the bed B atproper times.

I may use any well-known clutch between the driven wheels on the shaft Eto effect the movements above described. I prefer to employ thewell-known pawl-and-ratchet clutching device.

The pillow-block c is extended upwardly and provided with an overhanging bracket I), which affords the bearings for the spindle of a crane Q,the free end of the arm of which has depending from it a block andtackle, (shown in Fig. l of the annexed drawings,) to the lower block ofwhich is hitched a bail R. This bail is provided on the lower ends ofits arms with hooks h, which are designed to grapple or engage withbutton-head studs n formed on the ends of the mold T at the middle ofthe width thereof. The bail R affords such a large arch that the mold Tand a truck V can be at the proper time lifted from the bed B and turnedover, leaving the glass plate upon said truck, so that the latter can betransferred upon its wheels, plate upthe chase. y mold I fix studs t,four in number, which enter apertures made in the bed B and thus fix themold-chase in proper position for receivrover one end of the mold.

inner side bar of the main frame so that they can be adjusted to theplanes of the several track-rails N in the annealing-furnace, thusallowing the trucks to be moved from the molding-frame with theglassknpon their surfaces into the annealing-furnace, previous to whichthe trucks are unhooked from the mold T and the mold returned to itsplace upon the reciprocating bed B.

The mold B, which I have above described, is constructed somewhat like aprinters chase, having raised longitudinal sides q q and outwardly anddownwardly beveled ends q q', the flat tablet of the truck V beingadapted to fit snugly within the chase or mold and to be locked theretoby means of hooks h2 on the ends of the tablet engaging with thebutton-head pins n on the ends of On the bottom of the chase or ing themolten glass from the furnace, at the same time allowingit to be readilyremoved when desired.

The operation of my glass-molding may chine is as follows: The moltenglass is illowed `upon the mold T, which, like all parts of my l devicethat contact with the glass, is kept at `a given heat by the means abovedescribed. The bed is moved beneath the cylinder D,

and the surplus glass is forced upon the bed When the mold has fullypassed the cylinder, a truck-plate V pis adjusted upon it, and the hooksh2 are engaged with the studs n on the mold frame or chase T. The hookson the bailR are then engaged with the studs fn, and the mold, togetherwith the truck-plate V, is lifted and reversed, so that the truck-wheelsw are in alignment with the hinged rails O at one end of the main frameA. The crane is then swung, and the truck with the molded glass upon itsupper side is run into the annealingfurnace M upon the stationary railstherein. The process is repeated automatically at each IOO IIO

terminus of the stroke of the bed B, using two doors M M for theannealing-furnace M. It will be observed that the rectilinearreciprocating movements of the-bed B are strictly automatic, by reasonof this bed touching the push-rods r at the termini of its strokes, thesaid rods operating to shift the clutch on the shaft E to give theforward and backward movements to the bed B.

Having described my invention, I claiml. In a glass-molding machine, thecombination, with the reciprocating mold-bed thereof, of a crane adaptedto swing horizontally A over the bed, a block and tackle carrying adepending bail having hooks at its lower ends, and a truck adapted toset over the 3. The combination, in a glass-moldin g machine, of thetrack-frame, the reciprocating mold-bed arranged to travel thereon, andthe 15 truck and connections whereby the said truck may be secured tothe mold to hold the two together, substantially as specified.

In testimony whereof I affix my signature in presence of two Witnesses.
